The mean absolute deviation of the number of books is 1.84
<h3>How to determine the mean absolute deviation?</h3>
The dot plot of the number of books is in the attached figure.
From the figure, we have:
x f
1 1
2 2
3 2
4 3
5 1
6 2
7 3
8 1
Start by calculating the mean using:
So, we have:
Evaluate the sum and products
Divide
The mean absolute deviation is then calculated as:
So, we have:
Evaluate the absolute difference
Evaluate the sum of products
Divide
Hence, the mean absolute deviation of the number of books is 1.84

Answer:
Angle BAF and angle BAC is incorrect.
They overlap: adjacent angles do not overlap.
Answer:
A
Step-by-step explanation:
-2 5/6, -2/3, 1 1/6, 1 5/6
Are all ordered from least to greatest
x^3 = 5x
Subtract 5x from both sides:
x^3 - 5x = 0
Factor X out of x^3:
x(x^2-5x) = 0
Set X to 0 and solve for x:
x = 0
Set (X^2-5) to equal 0 and solve for x:
x^2 - 5 = 0
Add 5 to both sides:
x^2 = 5
Take the square root of both sides:
x = √5, -√5
The three solutions of x are 0, √5, -√5
In order from smallest to largest = -√5, 0, √5
The largest possible value is √5
Answer:
x>=-3
Step-by-step explanation:
-4x-10<=2
-4x<=2+10
-4x<=12
x<=12/-4
x<=-3
x>=-3
